Eating dessert throughout the week may help dieters lose more weight. Studies show that overweight girls lose more weight and tend to stay on a healthy diet if they eat sugar-free, low-fat desserts several times a week as opposed to a full calorie, high sugar dessert once a week. Pediatrician and research fellow at Athens University School of Medicine in Athens, Greece, Antonia Dastamani, M.D., PhD states, "Dieters commonly splurge on a dessert once a week, usually choosing a fattening item. However, we found a positive effect of more frequent consumption of desserts that have a low glycemic index and low glycemic load."
